Led Effects On Kick Scooter

Hans Did great work on Arduino – All LEDStrip effects in one (NeoPixel and FastLED) and put light effect changing with a press of a button.

Now i want to put this project on my scooter. To do that  My challenge is adding some functionality to button. I want to put the project on my diy electric scooter so 1 button is good for cable harness optimization . The button in the project is only changing the effects ,so;

1- I need to add a long press turn off/turn on functionality  which starts from the last animation before turning off. Someone asked a question like that in the comments but i see this is not easy. 

2- Double press the button to change and set the color of the effect.

So in summary the button,

1 short press change the effect

2 short press change and set the color

1 long press turn off /on

Is it possible?I am a very newbea and tried lots fo things before posting, is there a way to do this by adding/changing the code below?, 

Thanks

Hans's Code:

#include "FastLED.h"
#include <EEPROM.h>
#define NUM_LEDS 60
CRGB leds[NUM_LEDS];
#define PIN 5

#define BUTTON 2
byte selectedEffect=0;

{
  FastLED.addLeds<WS2811, PIN, GRB>(leds, NUM_LEDS).setCorrection( TypicalLEDStrip );
  pinMode(2,INPUT_PULLUP); // internal pull-up resistor
  attachInterrupt (digitalPinToInterrupt (BUTTON), changeEffect, CHANGE); // pressed
}

//  REPLACE FROM HERE

  EEPROM.get(0,selectedEffect);

So in summary the button,

1 short press change the effect

2 short press change and set the color

1 long press turn off /on

Hi Atatan!

I have a few questions before we dive in ...

Changing color:
I assume you have a specific effect in mind, since some effects change colors all the time.
Did you want to implement all effects? Or just a handful?

Turning On/Off:
The Arduino does not have a On/Off possibility - the Arduino will always be ON unless you pull the power cord.
The only thing we can do is toggle between effect(s), or the LED strip is not showing anything (dark).
Is that what you mean?

While tinkering a little with this I just realized ... do you have a fixed set of colors in mind when talking about the changing color?

Also just realized that we cannot use certain functions in the function that is being called by the interrupt.
For example "millis()" will not produce useful data, eg. it doesn't increment while in this function is running so we cannot use it for timing.

So ... to get even close to what you're looking for, we will need to change more than just reading the button.
I'm still tinkering with this, so maybe I'll come up with something that works ...

It took me pretty much the entire afternoon, and I'm still not 100% happy with it.

Here for what I did come up with today.
Note: It doesn't do anything with the button presses yet.
It's just reading the button presses and set a variable to true or false (ChangeEffect, ChangeColor, SwitchOnOff).
Up to you to see where and what to do based on those variables.

A few pointers;

Since we're doing potentially would be doing more in the interrupt function, I changed the way things work a little.

1) The interrupt function only logs if a button was pressed or released. (function is now called CatchButtonInterrupt() )

2) When calling showStrip() (which happens quite often in the effects), the function HandleButtonChanges() will be called to see what is happening and what this means for the 3 variables (ChangeEffect, ChangeColor, SwitchOnOff).

In HandleButtonChanges you'll see this little IF section, which right now just prints something to the serial monitor.

if (ChangeEffect) { Serial.println("TASK: Change Effect (single press)"); }
else if (ChangeColor)  { Serial.println("TASK: Change Color (double press)"); }
else if (SwitchOnOff)  { Serial.println("TASK: Toggle ON / OFF (hold)"); }
else { Serial.println("TASK: -- something went wrong --"); }

 

 I hope that makes sense 😊 

The code also still needs to be cleaned, and normally I'd even comment out the debug code or remove the debug code.
I left it though, so you can see what it does.

You'll notice that buttons can be a little finicky on an Arduino.

In case you're wondering about debouncing: we're using the internal pull-up resistor, but this may not be enough.
You can optionally place a 10 KOhm resistor between the +5V and the button pin (pin 2) of the Arduino, which makes the button behave a little better.

Here is the code so far:

Note: if there are only a few effects you'd like to use, then we can clean up even more by removing the unwanted ones.
We could even optimize it more for FastLED.

#define FASTLED_INTERNAL    // just used to mute the Pragma messages when compiling
#include "FastLED.h"
#include <EEPROM.h>

#define DEBUG

#define NUM_LEDS 60
CRGB leds[NUM_LEDS];

#define LED_PIN    5
#define BUTTON_PIN 2

byte selectedEffect=0;

unsigned long FirstButtonPress  = 0;
unsigned long ButtonReleased    = 0;
unsigned long SecondButtonPress = 0;

volatile boolean ButtonWasPressed  = false; // catch if a button was pressed
volatile boolean ButtonWasReleased = false; // catch if a button was pressed

boolean ChangeEffect     = false; // single press
boolean ChangeColor      = false; // double press
boolean SwitchOnOff      = false; // hold press

#define MaxButtonDelay 2000 // have a x millis second window to check button changes

void setup()
{
  FastLED.addLeds<WS2811, LED_PIN, GRB>(leds, NUM_LEDS).setCorrection( TypicalLEDStrip );
  
  pinMode(BUTTON_PIN,INPUT_PULLUP); // internal pull-up resistor
  
  attachInterrupt (digitalPinToInterrupt (BUTTON_PIN), CatchButtonInterrupt, CHANGE); // attach interrupt for when pin goes from LOW to HIGH
  
  Serial.begin(19200);
}

So in summary the button,

1 short press change the effect

2 short press change and set the color

1 long press turn off /on

Hi Atatan!

I have a few questions before we dive in ...

Changing color:
I assume you have a specific effect in mind, since some effects change colors all the time.
Did you want to implement all effects? Or just a handful?

Turning On/Off:
The Arduino does not have a On/Off possibility - the Arduino will always be ON unless you pull the power cord.
The only thing we can do is toggle between effect(s), or the LED strip is not showing anything (dark).
Is that what you mean?

Hi Hans thanks for reply. 

Changinging color is a good question.Gor example at rainbow(which is awesome) there are all colors in it. Or fire has a essential red. To summarşze, there are some effects in your code which are automatically changing colors, ore some has fixed colors.We can change the colors of theese animations. But ny personall favorite animations are ;RGBLoop, FadeInOut, Strobe (Left/right) , kitt, Sparkle, SnowSparkle, Running Lights, colorWipe, rainbowCycle, theatherChase, theaterChaseRainbow, Fire, meteorRain.

When color changes by double click is it possible to fix selected color? For example you are on 3rd animation normally starts with white and i set the color to red by double clicking..After changing animation an turn back to 3rd animation again it starts with red.

Turning off is yes you are right.Dark is ok. After setting the dark animation (off) and then while long pressing the button by turning on it will be good if the animation starts where it left.

 

Thanks

For the effects that are based on a fixed color, we could define a global CRGB variable, to which we assign the "active" color.

Something like this at the beginning of the code:

CRGB ActiveColor;

 

Then in the code of a function, for example RunningLights

void RunningLights(int WaveDelay) { // removed: byte red, byte green, byte blue, 
  int Position=0;
 
  for(int i=0; i<NUM_LEDS*2; i++)
  {
      Position++; // = 0; //Position + Rate;
      for(int i=0; i<NUM_LEDS; i++) {
        setPixel(i,((sin(i+Position) * 127 + 128)/255)*ActiveColor.red,
                   ((sin(i+Position) * 127 + 128)/255)*ActiveColor.green,
                   ((sin(i+Position) * 127 + 128)/255)*ActiveColor.blue);
      }
     
      showStrip();
      delay(WaveDelay);
  }
}

 

And call RunningLights like so:

// optional set the ActiveColor first
ActiveColor = CRGB(0xff,0x0x,0x00);

// then call the effect
RunningLights(50);  // red

 

When doing a double press, all you need to do is select a different color for ActiveColor and the effects that use it, will show that color.

To select a color you'd probably need to define a list (array for example) of colors, and keep track of the selected color in a global variable.

As you can see; it is all very possible, but it will take some work to adapt the code. 😊
